 * Calendar 日历
 * @description 日历组件可以查看日期，选择任意范围内的日期，打点操作。常用场景如：酒店日期预订、火车机票选择购买日期、上下班打卡等
 * @tutorial https://ext.dcloud.net.cn/plugin?id=56
 * @property {String} date 自定义当前时间，默认为今天
 * @property {Boolean} lunar 显示农历
 * @property {String} startDate 日期选择范围-开始日期
 * @property {String} endDate 日期选择范围-结束日期
 * @property {Boolean} range 范围选择
 * @property {Boolean} insert = [true|false] 插入模式,默认为false
 * 	@value true 弹窗模式
 * 	@value false 插入模式
 * @property {Boolean} clearDate = [true|false] 弹窗模式是否清空上次选择内容
 * @property {Array} selected 打点，期待格式[{date: '2019-06-27', info: '签到', data: { custom: '自定义信息', name: '自定义消息头',xxx:xxx... }}]
 * @property {Boolean} showMonth 是否选择月份为背景
 * @event {Function} change 日期改变，`insert :ture` 时生效
 * @event {Function} confirm 确认选择`insert :false` 时生效
 * @event {Function} monthSwitch 切换月份时触发
 * @example <uni-calendar :insert="true":lunar="true" :start-date="'2019-3-2'":end-date="'2019-5-20'"@change="change" />
